The property you're describing is called fluidity.

Fluidity refers to a liquid's ability to flow easily. The more fluid a liquid is, the faster and more readily it moves.

Here are some other related terms:

* Viscosity: This is the opposite of fluidity. A liquid's viscosity is its resistance to flow. The higher the viscosity, the slower the flow.

* Low viscosity: This means a liquid is very fluid and flows quickly.

* High viscosity: This means a liquid is not very fluid and flows slowly.
